JOURNAL-BOX.

Specification of Letters Patent.

ratented April 23, 1907.

Application filed April 4, 1906. Serial No. 309,855.

To all whom it may concern.-

Be it known that I, WVIL L-mi STEVENSON, a citizen of the United States,and a resident of Chicago, Cook county, Illinois, have invented acertainnew, useful, and Improved J ournal-Box, of which the following isa full, clear, and exact description, such as will enable others skilledin the art to which it pertains to make and use the same.

My invention relates to journal boxes for car trucks and has specialreference to improvements in journal boxes of that class wherein the lidis held by a horizontal hinge on the top of the box.

The object of my invention is to simplify and otherwise improve theconstruction of journal boxes of the above mentioned class, andparticularly to improve the means for holding the journal box lidtightly closed, also, when desired in its opened position.

The special object of my invention is to provide a journal box lid thatshall completely close the journal box opening, and to provide meansupon the exterior of the box for looking or fastening such lid; adistinct purpose of my invention being to avoid the use of openings inthe lid or the use of springs or other devices necessitating eitheropenings or channels in the lid, through which dust might enter the box.

The particular object of my invention is to provide a journal box whichshall have an externally locked or spring-pressed lid that shall beinterchangeable with the lids of the so-called Master Car Builders type.

A further object of the invention is to provide a journal box having aspring pressed lid and whereof the spring shall be completely enclosedand protected.

Other objects of my invention will appear hereinafter.

My invention in its preferred form coinprises a journal box, incombination with a id, hinged at the top of the box and provided with alocking lug or cam on its upper end and a spring device on the top ofsaid box parallel with the hinge of the lid, and coacting with saidlocking lug or cam to hold said lid in either closed or opened position.

My invention also consists in various details of construction and incombination of parts all hereinafter described and pointed out in theclaims.

stood by reference to the accompanying drawings, forming a part of thisspecification and in which I have illustrated that form of -inyinvention which I prefer:

In said drawings, Figure 1, is a vertical section of a journal box,embodying my invention, the section being on the line a'w, of Fig. 2,Fig. 2 is a plan view of a ortion of the top of the box and lid, and,lig. 3, is a sectional detail, showing the lid in opened position; andalso illustrating a slight modilication.

My invention is not limited to a journal box of special form, in otherwords, it is applicable to any of the journal boxes in ordinary use.

The journal box, A, here shown, conforms substantially to the rules ofthe Master Car Builders Association, being provided with an end opening,A, and a hinge lug, A, of the types prescribed by said rules. The formof the box is neither changed nor altered to suit my invention exceptthat the top of the box is provided with an additional lug, A", Thislast, is parallel with the hinge lug, A and is separated therefrom by aspace of suilicient size to admit the hood or top of an M. C. B. whensuch is substituted for the lid hereinafter described. The lug, A,contains the usual hinge pin, C. The lug A, contains an opening that isparallel with the hinge pin and in this I arrange preferably twoplungers, D, D, and a spring, D, the latter being adapted to project theplungers from the ends of the lug, A, upon a line or axis parallel withsaid hinge.

My novel lid, B, has hinge lugs, B 13 ournaled on the hinge pin, C, Theflange, B of the lid extends entirely around the end of the box. The lidis solid, containing no openings through which dust may enter the box.On the lid lug, B are two locking lugs or cams, B The inner faces of thelugs, B, are preferably curved, as shown, and the lugs are so positionedas to engage the rounded or tapered ends of the plungers D. D. Thelatter are forced outward by the strong spring D, and wedging against orunder the lugs B firmly lock or hold the lid upon the end of the journalbox. The spring-fastening, thus formed, is of such effectiveness, thatconsiderable force is required to open or raise the lid. When the lid islifted, the lugs, B B,

The invention will be more readily under- 1 force the plungers D, D,into the lug or holder A, but as soon as the lugs pass the centers orcrowns of the plungers, the latter spring out and force the lugsdownward, thereby assisting in the raising of the lid and securelylocking the lid in open position. When desired, I provide the lid with ahood, B, as shown by dotted lines in Figs. 1 and 2 and in full lines inFig. 3 and in such cases the cams, B are formed within the ends of thehood.

It is obvious that various modifications of my invention as hereinshown, will readily suggest themselves to one skilled in the art and Itherefore do not confine my invention to the specific constructionherein shown and described.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A journal box, having a hinge lug, in combination with a lid, ahinge-pin, a cam on said lid and a longitudinally acting spring deviceon said box parallel with the axis of said hinge pin and co-acting withsaid cam, sub stantially as described.

2. A journal box, in combination with a lid, hinged at the top thereofand provided with a lug or cam adjacent to the hinge and a spring deviceon said box, said spring device being parallel with the axis of saidhinge and coacting with said cam, to secure said lid in closed and openpositions, substantially as described.

3. A journal box, in combination with a lid, hinged on said box andprovided with a locking lug or cam and a spring device constantlyengaged with said lug and co-acting therewith upon an axis parallel withthe axis of the hinge of said lid, substantially as described.

4. A journal box, in combination with a lid hinged thereon and providedwith a pair of lugs or cams and a spring device acting upon an axisparallel with the hinge axis of said lid and abutting said camssubstantially as and for the purpose specified.

5. A journal box having a hinge lug and hinge pin, in combination with alid, provided with a lug or cam, a plunger movable upon an axis parallelwith the axis of said hinge pin and constantly engaged with said lug onsaid lid, and a spring pressing upon said plunger, substantially asdescribed.

6. A journal box, in combination with a lid, hinged thereon and providedwith a pair of lugs or cams, a co-acting spring, arranged upon the topof said box parallel with the hinge axis of the lid and between saidlugs, substantially as described.

7. A journal box, in combination with a lid hinged thereon, a springholder on said box, a horizontally acting coiled spring held thereby,said spring being parallel to the hinge axis lugs or cams on said lidand plungers interposed between the same and said spring, substantiallyas described.

8. A journal box provided with a hinge lug, in combination with a lidhaving hinge lugs, a hinge pin, there being locking lugs or cams on thehinge lugs of said lid and a locking spring arranged on said box betweensaid locking lugs and co-acting with the latter, substantially asdescribed.

9. A journal box, having a hinge-lug, in combination with a lid alsohaving hinge lugs, a hinge pin, a second lug on said box, parallel withits hinge lug, a coiled spring and plungers arranged in said second lug,said plungers having convex ends and coacting cams on said lid,substantially as described.

10. A journal box, provided with parallel hinge and spring lugs upon itstop, a hinge pin, a lid, pivoted on said pin and provided with a lockingcam, a spring-pressed lunger in said spring lug and a hood on said idpartially enclosing said parallel lugs, substantially as described.

11. A journal box having a hinge lug in combination with a hinge pintransverse to the axis of the box, a lid hinged on said pill andprovided with two cams, a spring device arranged on the top of said boxand movable upon an axis parallel with the axis of said hinge pin, saidspring device constantly coacting with said cams to secure said lid inclosed and open positions, substantially as described.

In testimony whereof I have hereunto set my hand, this 29th day ofMarch, 1906, at Chicago, county of Cook and State of Illinois, in thepresence of two subscribing witnesses.

WILLIAM STEVENSON.
